I would love the black flames that was in the initial reveal, but unless they completely reprogram how said effects are displayed on, amongst other things, mounts I'm afraid we won't be getting it. And you know how things go in reprogramming. Change one thing, affect ten others. With the time-constraints the FFXIV team most likely has, they're having to make choices. I can understand them putting this on the long-burner, if even that.
